To aZZ whom it may concern/.-

Be it known that I, FREEBORN F. RAYMOND,

and exactdescription, reference being had to the accompanying drawings, forming a part of this specication, in explaining its nature.

It is customary in the manufacture of boots and shoes to temporarily attach an outsole to the insole to hold it centered thereon during the operation of the sewing-machine or other devices for permanently fastening them together, and heretofore this has been accomplished by placing the outsole upon the insole, temporarily attaching it thereto by a few nails driven singly and in successive order. The shank and fore part are then permanently fastened bysewing or by metal fastenings, and the heel end of the sole then fastened by nails driven by hand or by machine in successive order, and the sole thus fastened is then submitted to the action of a beating-out machine, whereby the soles are shaped to the form of the beatingout last. v

My invention has for its object the expediting ofV these various steps by merging or consolidating them; and it consists, essentially,

.in shaping the outsole upon the insole by a suitable pressure-plate having a form the counterpart of the form of the upper surface of the last or work-support upon which the boot or shoe is mounted, and while the outsole is thus held, shaped, and compressed upon the insole to temporarily attach the shank and fore part thereto bya few fasten-ings simultaneously driven, and at the same time permanently fastening the heel end of tli'e outsole' to the upper and insole, and by a gang of fastenings simultaneously driven and placed quite closely or comparatively closely together, so

that the boot or shoe has its outsole shaped to the desired form before the permanent fastening of the shank and fore part is done, and the heel end of the outsole permanently fastened tothe upper and insole before the shank and fore part are permanently fastened. I prefer to drive the fastenings for temporarily attaching the shank and fore part and a fastening used for permanently securingthe heel end of the outsole simultaneously, although this is not essential.

By fastening the heel end of the outsole per- 55 manently before the shank and fore part are permanently secured fewer fastenings are needed for holding the outsole in place during the said permanent fastening of these parts.

Where the work is to be channel sewed or nailed, the pressure-plate is provided with a recess for receiving the lip or skived section of the sole, in order that the'fastening may be Y placed in the section of the sole uncovered by this lip or skived part. Of course only the shank and fore part of the sole is provided with this channel.

In 'the drawings, Figure 1 represents in elevation and vertical section a shoe mounted upon a last or Work-support and an unformed outsole above the same placed. in position to be molded or formed by the operation of the pressureplate, Fig. 2 represents the same parts and in addition the pressure-plate, which is represented as molded or formed to the outsole close to the-surface of the last or Worksupport. Fig. 3 is avertical section upon the line a: x of Fig. 2. Fig. 4 is a plan view, reversed, of the pressure-plate. Fig. 5 is a view in plan, inverted, of a boot or shoe having the outsole permanently fastened to the upper and insole at the heel and the shank and fore part temporarily fastened to the insole, the lip or skived section of the sole being represented as still turned backward to4 expose the channel. Fig. 6 is a view in perspective of a fastening.

In the drawings, Ais the last or Work-support. ais the jack-spindle. a is the outsole; a2, the insole, as, the upper; a4, the pressureplate. It has the holes ai", through which the fastenings are driven, and a recess, c, in its under surface for receiving the lip or skived section a7 of the outsole. It also has the forming face or cavity of, which is substantially parallel withthe upper surface, a, of the last or Work-support.

I prefer to use as a fastening a staple having two fastening-prongs of substantially the shape shown in Fig. 6, although I do not confine myself to this form of fastening; but I prefer it, as it forms a very rigid and secure fastening, and necessitates the driving of a less number than if the ordinary one-prong fastening were used.

Of course if the Sole is not channel nailed or sewed there is no necessity for providing the templet with the lip-holding cavity a, and Where it is not channel nailed or sewed it will be desirable to use staples or tivo-prong fastenings only for the heel and small nails'for the shank and fore part.

In practicing the invention theontsole is placed upon the last or work support, the pressureplate moved upon it., as represented in Fig. 2, the fastenings fed to the holes therein and driven simultaneously' by a. gang orgroup of drivers, (which nre not shown, but which are like those described in various of my patents,) While the plate holds the outsole cornn pressed upon the upper and insole.

I would here say that it is not necessary to form the outsole to the insole before driving the fastenings, and that the fastenings for permanently securing tbe heel may be first driven before those for temporarily securing the shank and fore part are driven.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- The method of laying outsoles, consisting in permanently fastening the heel end of the outsole to the insole by a gang or vgroup of fastenings and the shank and fore part of the sole to the insole by temporary fastenings driven simultaneously with the permanent heel-fastenings, substantially as described.
